Given that pistons have two ports, and pumps only one, the compressor geometry
would not work. With a slight modification to twist the pistons 90 degrees, and
larger spacing between the tri-blade parts (my new favorite part), it fit
together nicely.
The six pistons are broken up into three pairs. A given pair drives one switch.
I've found that two small pistons to one switch is a good ratio. The switch
drives the next piston pair in sequence.
The integral stud spacing between the tri-blades allows for better structural
reenforcement without much cross bracing compared to the compressor. The
compressor had 1.5 stud spacing between tri-blades, making it difficult to make
as structurally strong.
(...) Great! How does it preform? What is the RPM? (when connected to your compressor & when pumped by hand) What is the torque? - David (19 years ago, 17-May-05, to lugnet.technic, lugnet.robotics)
(...) <snipped the rest> Well, well well. Small is beautiful. Be it pumps or cylinders. Great work! CS (19 years ago, 18-May-05, to lugnet.technic, lugnet.robotics)
